The plastics suction mould joint
Technical field
The utility model relates to a kind of plastics suction mould joint.
Background technique
Plastics suction mould is in when work, carries out jetly in a side of diaphragm, and it is air-breathing that opposite side utilizes vacuum suction device to carry out, and makes diaphragm both sides produce pressure difference, thereby diaphragm is pasted on mould.At present, be to utilize rapid pipe joint that vacuum suction device is connected on mould.To be threaded between the exhaust tube of rapid pipe joint and vacuum suction device.But screw-thread fit the time, gas can be from seepage in thread gaps, thereby tightness is not high, easily causes vacuum suction device gas leakage; And because the weight of exhaust tube is large, needing when mounted to overcome very large torsion could be connected to rapid pipe joint on exhaust tube.
The model utility content
The purpose of this utility model is in order to overcome deficiency of the prior art, a kind of plastics suction mould joint that can easily plastics suction mould be connected with vacuum suction device to be provided.
For realizing above purpose, the utility model is achieved through the following technical solutions:
The plastics suction mould joint is used for connecting plastics suction mould and vacuum suction device, it is characterized in that, comprises the first pedestal of hollow and the second pedestal of hollow, described the first pedestal and described the second pedestal clamping.
Preferably, described the first pedestal one end is connected on plastics suction mould, and described the second pedestal one end is connected on vacuum suction device.
Preferably, be concaved with draw-in groove on the circumference of described the first pedestal one end; The end that described the first pedestal is provided with draw-in groove is plugged in described the second pedestal, and described the second pedestal is provided with buckle, and described buckle is stuck in described draw-in groove.
Preferably, described buckle is arranged at described the second pedestal both sides rotationally, and described buckle comprises snapping section and handle part, and described snapping section is stuck in described draw-in groove.
Preferably, described buckle is arranged on described the second pedestal rotationally by bearing pin.
Preferably, described buckle number is more than two, distributes along the second pedestal circumferencial direction.
The utility model plastics suction mould is set to clamping with joint by the first pedestal and the second pedestal and coordinates, and replaces traditional screw-thread fit, makes the heavy exhaust tube that need not rotate on vacuum suction device, thus convenient the installation.In addition, the first pedestal and the second pedestal are set to clamping and coordinate, and make to be connected closelyr between plastics suction mould and vacuum suction device, and gas is seepage among the thread gaps no longer, and tightness strengthens.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail:
As shown in Figure 1: plastics suction mould is used for connecting plastics suction mould 2 and vacuum suction device (not shown) with joint 1.This plastics suction mould comprises the first pedestal 11 of hollow and the second pedestal 12 of hollow with joint 1.The first pedestal 11 and the second pedestal 12 clampings.
The first pedestal 11 1 ends are connected on plastics suction mould 2, and the second pedestal 12 1 ends are connected on vacuum suction device.
Be concaved with draw-in groove 111 on the circumference of the first pedestal 11 1 ends.The end that the first pedestal 11 is provided with draw-in groove 111 is plugged in the second pedestal 12, and the other end is connected on plastics suction mould 2.
The second pedestal 12 is provided with two buckles 121.Two buckles 121 along the circumferential direction distribute.Buckle 121 is arranged on the second pedestal 12 rotationally by bearing pin 122.Buckle 121 comprises snapping section 1211 and handle part 1212.Snapping section 1211 is stuck in draw-in groove 111.
Details are as follows with the joint working principle for plastics suction mould of the present utility model:
During work, first the first pedestal 11 and the second pedestal 12 are separately fixed on plastics suction mould 2 and vacuum suction device.End insertion second pedestal 12 that the first pedestal 11 offers draw-in groove 111 is provided with in an end of buckle 121.Then, to the first pedestal 11 direction handle with sleeve sections 1212, make snapping section 1211 be stuck in draw-in groove 111.
The utility model plastics suction mould by the first pedestal 11 and the second pedestal 12 are set to the clamping cooperation, replaces traditional screw-thread fit with joint 1, makes the heavy exhaust tube that need not rotate on vacuum suction device, thus convenient the installation.In addition, the first pedestal 11 and the second pedestal 12 are set to clamping and coordinate, and make to be connected closelyr between plastics suction mould 2 and vacuum suction device, and gas is seepage among the thread gaps no longer, and tightness strengthens.
Embodiment in the utility model only is used for the utility model is described, and does not consist of the restriction to the claim scope, and other substituting of being equal in fact that those skilled in that art can expect are all in the utility model protection domain.
